-Application filed. December 10, 1924. Serial No. 755,051.

This invention relates to Weaving and more particularly to the weaving of pile fabric, an object of the invention being to provide a method of weaving fabric with an'uncut pile in which two pieces of fabric are woven with their faces together, and are severed or separated without requiring the cutting of the pile and a process or method which eliminates the use of either solid or elastic supports running parallel with the warp threads.

. More specifically, the invention comprehends the method of weaving pile wherein certain of the filling threads are positioned outwardly and in proximity to the outer sides of the woven fabric, said filling threads serving as supports for the loops of the pile of the fabric.

Other objects of the invention will appear in the following detail description, and 1n the accompanying drawings wherein:

Figure 11s a view showing the longitudinal section on an enlarged scale through the fabric prior to the separation of the two pieces.

Fi ure 2is a view similarto Figure 1 showing one of the pieces separated.

Figure 3-is a section through a modified form of fabric on an enlarged scale.

Figure 4-is a section throu h still another form of fabric on an enlarge scale showing fabric of closely positioned or related piles.

Referring more particularly to the drawings, the fabric shown in Figure 1 is composed of warp threads 1 and 2, which are used in connection with the transverse filling threads 3 in the weaving of the fabric. In weaving the fabric, two sections or pieces of fabricare woven with their faces towards each other, and the pile warp threads 5 of the piece of fabric A are passed through the piece of fabric B and looped over the supporting filling thread 4, and returned to the piece of fabric A forming a pile warp, as shown at 5, and the pile warp thread 5 of the piece of fabric B is passed through the piece of fabric A and over I the supporting filling thread 4 thereof, and returned to the piece of fabric B for forming a pile for the piece of fabric B.

By particular reference to Figure 1 of the drawings, it will be noted that the supporting filling threads 4 are placed against the outer surface or sides of the pieces of fabric A and B respectively, and in the pieces of fabric A and B the respective pile warp threads 5 are passed over and under alternate fillin threads 3, prior to their return to and throug the 0p posite piece offabric. As shown in Figure 1 of the drawings, the respective pile warp,

threads 5 are passed over and under three filling threads before a subsequent pile loop isformed, thus spacing the pile loops at deslred predetermined distances apart. After the fabric has been woven, I the supporting filling threads 4 are withdrawn which releases the connection of the pieces of fabric A and B and permits them to be separated, leaving the pile loops 5 intact and eliminating the necesslty of cutting for the purpose of separating the pieces. In the type of fabric shown in Figures 1 and 2, the pile loops from the two pleces of fabric are placed in parallelism and in lateral alignment with each other. The

.arrangement of the pile loops in parallelism and lateral alignment with each other is also carried out in the modified form shown in Figure 3 of the drawings. In this form,

however, the pile loops 5 are spaced a greater.

distance apart than in the form shown in Figures 1 and 2, and the warp threads 1 are passed over two and under two of the filling threads, 3. It is understood, in both forms that the warp threads are woven in with the filling threads in the usual manner. The pile 'loops 5' are passed over supporting filling threads 4:, which threads are afterwards withdrawn when the fabric is completed permitting the severing of the two pieces.

In Figure 4 of the drawings, a modified form of fabric is shown in which the pileloops are placed in close proximity to each other, with, the pile loops 5 of the section 0 of fabric, being disposed alternately to the pile loops 5 of the piece of fabric D, and it will also be noted in this preferred form, that the supporting filling threads 4 which are positioned outwardly of the outer surfaces of the pieces of fabric C and D alternately with the filling threads 3". The filling threads 4* are Withdrawn after this form of fabric is woven to permit separation of the two pieces of fabric C and I). 7

It is, of course, to be understood, that the invention may be constructed in various other manners and the parts associatedin different relations, and therefore, I do not desire to be limited in any manner, except as set forth in the claim hereunto appended.

What I claim is:

A method of forming pile fabrics, consisting in weaving interconnectingly together two sections of fabric, weaving a plurality of of temporary pile supporting threads with the two sections and ositioning the temporwarp threads over said pile supporting 10 ary pile supportin t reads adjacent the rear threads, forming a series of loops in each of faces of the mdivi ual webs of fabrics, weavsaid fabric sections, aralleling and aligning ing a series of warp threads to interlace filler the series of loops, aterally positioning the 5 threads in each web, then loop over the pile loops, and finally withdrawing said pile supsupporting threads-at the rear of the opposite porting threads to permit separating of sad '15 web, then return to the filler threads of the sections of fabric. first web with which the interlace for a pre- In testimony whereof I aflix m signature. determined distance, and again looping said FERDINAND W.
